Abstract: PROBLEM TO BE SOLVED: To obtain a disk turning and driving apparatus by which a disk is chucked stably by a method wherein a rotating plate which is turned integrally with a turning and driving shaft coupled to a center hole is provided and a driving pin which erected and installed at the rotating plate so as to be directly slidable is coupled to a disk driving hole. SOLUTION: A rotating plate 23 is fixed to a turning and driving shaft 21, and a hub receiver face 28 on which a disk is placed is formed around the shaft 21. A long hole part 25 is made in the rotating plate 23 so as to keep a constant radial distance from a virtual fulcrum 24. The insertion part of a driving pin 26 is play- inserted into the long hole part 25, a slight gap is left in such a way that the flange part of a fixation pin 27 and the step part of the pin 26 are faced on both sides of the rotating plate 23 so as to be slidable, and the pin 27 is force-fitted to a hollow hole in the pin 26 from the lower side of the rotating plate 23. Thereby the pin 26 is erected and installed so as to be directly slidable along the long hole part 25 in the rotating plate 23. The sliding track of the pin 26 becomes the same as the track of the driving pin 26 provided with a turning lever.  The driving pin 26 and the fixation pin 27 are formed of an oil-impregnated alloy material so as to reduce a sliding loss with reference to the hole part 25.

Abstract: PURPOSE:To always allow an operation to follow up a reproducing signal of a high speed and a high density, and to stably detect data by comparing intermittently frequencies and phases of a reproducing signal and an output signal of a servo-oscillating circuit. CONSTITUTION:An output pulse SV of a voltage control oscillator VCO becomes an input of a DFF 12, and to its output Q, an SV-2 having a frequency of 1/2 of an output pulse SV of the VCO is outputted. A clock signal SP-1 which is inputted to an FF 11 is not an MFM read pulse SR but becomes OR of SR-2 and SR. Accordingly, when SR-2 is a high level, a charge signal SC becomes a high level by rise of the pulse SR. As a result, a reset signal SP-4 of an FF 15 becomes NOT AND of the signal SV-2 and a discharge signal SD. Also, when the signal SR is in a high level, the charge signal SC becomes a high level by a rise of the signal SR, and when the signal SC is in a high level, if the signal SV-2 falls, the signal SD becomes a high level.
